Muddiest point

Hey, guys. Heidi, here! I was wondering what the veins, arteries, and valves in the heart do. Thanks!

  1. the veins bring the blood back to the heart
    the arteries take take the blood from the heart to the rest of the body
    and the valves in the heart keep blood moving in one direction
